service.h

MPICH是MPI的重要研究,提供了一系列的接口函数,为并行计算的实现提供了编程环境.

//  MODULE: service.h
//
//  AUTHOR: Craig Link
//
//
//  Comments:  The use of this header file and the accompanying service.c
//  file simplifies the process of writting a service.  You as a developer
//  simply need to follow the TODO's outlined in this header file, and 
//  implement the ServiceStart() and ServiceStop() functions.
//  
//  There is no need to modify the code in service.c.  Just add service.c
//  to your project and link with the following libraries...
//
//  libcmt.lib kernel32.lib advapi.lib shell32.lib
//
//  This code also supports unicode.  Be sure to compile both service.c and
//  and code #include "service.h" with the same Unicode setting.
//
//  Upon completion, your code will have the following command line interface
//
//  <service exe> -?                to display this list
//  <service exe> -install          to install the service
//  <service exe> -remove           to remove the service
//  <service exe> -debug <params>   to run as a console app for debugging
//
//  Note: This code also implements Ctrl+C and Ctrl+Break handlers
//        when using the debug option.  These console events cause
//        your ServiceStop routine to be called
//
//        Also, this code only handles the OWN_SERVICE service type
//        running in the LOCAL_SYSTEM security context.
//
//        To control your service ( start, stop, etc ) you may use the
//        Services control panel applet or the NET.EXE program.
//
//        To aid in writing/debugging service, the
//        SDK contains a utility (MSTOOLS\BIN\SC.EXE) that
//        can be used to control, configure, or obtain service status.
//        SC displays complete status for any service/driver
//        in the service database, and allows any of the configuration
//        parameters to be easily changed at the command line.
//        For more information on SC.EXE, type SC at the command line.

//
//  PARAMETERS:
//    dwCurrentState - the state of the service
//    dwWin32ExitCode - error code to report
//    dwWaitHint - worst case estimate to next checkpoint
//
//  RETURN VALUE:
//    TRUE  - success 
//    FALSE - failure
//

//
//  FUNCTION: AddToMessageLog(LPTSTR lpszMsg)
//
//  PURPOSE: Allows any thread to log an error message
//
//  PARAMETERS:
//    lpszMsg - text for message
//
//  RETURN VALUE:
//    none
//
